What is the definition of matter?
Matter is anything that has mass and occupies space.
What are physical properties?
This type of property can be observed or measured without changing the substance's chemical identity.
difference between mass and weight?
mass measures amount of matter and weight is the gravitational force
what does a heterogenous mixture consist of?
Two or more phases
What is a mixture?
a combination of two or more substances in any proportion.
What is a pure substance?
A pure substance is a material made up of only one type of particle (atoms or molecules) and has consistent properties throughout.
What is volume?
The amount of space a substance occupies, this property depends on the size of the sample.
what is an example of an extensive property?
mass and volume
What are 4 types of mixtures?
Solution, collid, suspension, and separating mixtures.
What is solubility?
This property of a substance describes its ability to dissolve in another substance, like sugar in water.
How does the volume of a substance relate to its density?
Density is defined as mass per unit volume. The higher the volume for a given mass, the lower the density.
What is density?
This property, which describes a substance’s mass per unit volume, does not change with the amount of material.
example of an intensive property?
color, temperature, and solubility
what state of matter has a fixed volume but not a fixed shape?
liquid
What is mass?
This extensive property is the total amount of matter in a sample.
What unit of measurement is typically used to express the mass of an object?
The unit of mass is the gram (g) or kilogram (kg).
What is an extensive property?
This property changes when the amount of substance is altered.
what is one difference between a physical and chemical change?
Physical can be but chemical is usually irreversible
what does a gasses volume depend on?
Container due to the gas expanding to fit
What is a physical change?
This type of change occurs when a substance changes its appearance but not its chemical composition, like ice melting into water.
Give an example of a pure substance that can be classified as a compound.
An example of a compound is water (H₂O), because it is made of two elements, hydrogen and oxygen, chemically bonded together.
What is temperature?
This intensive property remains unchanged during a phase transition, like when ice melts to water.
what is plasma?
state of matter that resembles a gas but has some properties gasses do not have.
What is heat capacity?
This extensive property depends on both the quantity and type of material and represents the amount of heat energy required to change the temperature of a substance.
What is a chemical change?
This type of change involves a change in the substance’s chemical composition, like when iron rusts
